q/3 - 3 =6

add 3 to each side

q/3 = 9

multiply both sides by 3

q = 9 *3 = 27

All sides are the same, hence, all three angles are the same, and each one of them is 60 degrees. Due to that:

7x + 4 = 60

7x = 56

x = 56/7 = 8

8y + 12 = 60

8y = 48

y = 48/8 = 6

Inverse of y equals 12 to the x

e-lub [12.9K]

Answer:

$f^{-1}(x) = log_{12}(y)$

Step-by-step explanation:

We have the following function

y = 12^x, and we need to find the inverse function.

To find the inverse function we should solve the equation for "x". To do so, first, we need to:

1. Take the logarithm in both sides of the equation:

lg_12 (y) = log _12 (12^x)

(Please read lg_12 as: "Logarithm with base 12")

From property of logarithm, we know that lg (a^b) = b*log(a)

Then:

lg_12 (y) = x*log _12 (12)

We also know that log _12 (12) = 1

Then:

x = log_12(y).

Then, the inverse of: y= 12^x is:

$f^{-1}(x) = log_{12}(y)$
